SMOKING-PIPE Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed September 10 1907. Serial No- 392.102.

To all whom it may concern:

Be it known that-I, ROBERT J. MoMUR- RAY, a citizen of the United Statesof America, residing at California, in the county of \Vashington andState of Pennsylvania, have invented certain new and useful Improvementsin Smoking-Pipes, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to smoking pipes, and its primaryobject is, toprovide a pipe so constructed as to prevent the passage of nicotin intothe pipe stem.

A further object of the invention is, to provide a pipe which may bereadily taken apart and cleaned.

The construction of the improvement will be fully described hereinafterin connection with the accompanying drawing which forms a part of thisspecification, and its novel features will be defined in the appendedclaims.

In the drawing :F igure 1 is a longitudinal section of a pipe embodyingthe invention, Fig. 2 is a top plan view of the supplemental bowl or cupof the pipe, Fig. 3 is a bottom plan of the plug which carries thesupporting tube for the pipe-bowl, and Fig.

4 is a view in perspective of the pipe-bowl.

supporting tube detached.

The body portion of the pipe consists of the vertical member 1, havingan inwardly projecting tuhular extension 2 intermediate its ends, aforwardly projecting arm 3 near the lower end of said member 1terminating at its outer end in an integral cup 4, a forwardly pro tingcurvmi tube 5 being also connected to the member 1, near the upper endthereof, and at its outer end merging into the cup i.

The tubular extension 2 is formed with an internally threaded socket 6for the attachment of a stem 7 having a threaded nipple 8, fitting thesocket 6. A ferrule or'sleeve 9 is placed around the nipple connectionbetween the stem 7 and extension 2 to give additional strength to suchconnection.

The upper end of the member 1 is closed by a cap 10, and to its lowerend is attached a cap 11 formed with a threaded nipple 12 to which isreinovably secured a cap 13 provided with a pin 14 which projects intothe nipple 12.

Within the cup 4 is secured a diaphragm 15 formed with perforations 16for the passage of smoke, and with two oppositely disposed elongatedslots 17 said slots being Wider at one end than the other,

The reference numeral 18 designates a disk-shaped plug formed with acentral open-v ing 19 and provided on its under surface with twodiametrically opposite headed pins 20. To secure the plug 18 Within thecup the pins 20 are inserted through the enlarged ends of the slots 17after which said plug is given a partial revolution to engage the headsof the pins within the narrow portions of the slots. From opposite sidesof the opening 19 in the plug, project pins 21 for engaging the pipebowl supporting tube 22. This tube is formed with diametrically oppositelongitudinal grooves 23 and with horizontal grooves 24 on oppositesides. The upper end of the tube is formed with a semi-circular head 25and below said head the. tube is provided with horizontal grooves 25.The

pipe bowl 27 is open, at its base and provided with oppositelyprojecting pins 28.

To connect the pipe bbwl, the tube 22, and the plug 18, the tube 22 isinserted through the bowl and the latter is turned to engage its pins 28in thegrooves The tube 22 is then turned to engage the pins 21 in thegrooves 24 of the tube.

It will be apparent that a pipe constructed as thus described may bereadily taken apart for cleaning and also that the circuitous passagewhich the smoke is required to take eliectually prevents the entrance ofnicotin into the stem. The smoke is drawn down through the tube 22, theperforations 16 of the diaphragm, thence upward through the curved tube5 and downward through the member 1 before reaching the stem 7. The arm3 serves as a convenient hand-hold for the pipe.

Having fully described my invention What I claim as new and desire tosecure by Letters Patent, is

1. A pipe comprising a body portion having a passage therethrough, astern 3011- nected to the body portion and connnuruoating with thepassage thereof, removable caps on the ends of said body portion, an armprojecting forwardly from the body portion and terminating at itsforward end in cup, a tube connecting the bowl of said o with .thepassage in said body portion, on aperand a bowl detachably secured tosaid tube.

3. In a pipe the combination with a tubular body portion provided withan integral cup, of a perforated diaphragm secured Within said cup, aplug detaehably secured to said diaphragm, and having a central openmg,a bowl, and means for detachably connecting said plu and bowl.

4. In a pipe, he combination with a tubular body portion provided withan integral cup, of a perforated diaphragm secured with in said cup, aplug detaehahly secured. to

said diaphragm and having a central opening, a bowl, and means fordetachably eonnectlng said plug and bowl comprising a tube 111 said cup,a plu formed with longitudinal and horizontal grooves, and pinsprojecting from said plug and bowl.

-5. In a pipe, the combination with a tubular body portion provided withan integral cup, of a perforated diaphragm secured Withdetachablysecured to said diaphragm and havingta central opening, a bowl, andmeans for detachably connecting said plug and bowl, comprising a tubeformed with a semi-circular head fitting within the bowl and withlongitudinal and horizontal grooves, and pins projecting from said plugand bowl.

In testimony whereof I. aliix my signature in the presence oi twowitnesses.
